Building shadow length

How long a shadow does a 15 m high building cast if a 1-metre-long vertical rod casts a shadow of 90 cm at the same time? Include a sketch showing the similarity.

Final Answer:

x =  13.5 m

Step-by-step explanation:

b=15 m t=1 m y=90 cm m=90:100  m=0.9 m  t:y = b:x  x=b/t y=15/1 0.9=13.5 m
